We were out walking in snowy conditions yesterday when one of our party slipped on an icy rock and was consequently unable to stand. As it was obvious that something serious had happened we called out the mountain rescue.

In the meantime we used one of your survival bags to keep the injured person warm as can be seen in the attached photos.

I have no hesitation in recommending your survival bag which kept him warm until rescue by the helicopter and two teams who made it to us on foot.
